Patent DE-2445766-A1 (DE)
Title: High power electric generator - has its windings arranged to give axially directed magnetic fields to give high output
Inventor: GEIGER OTTO
IPC: H02K19/34
Filed: 1974-09-25
Abstract: On the rotor of this generator are arranged sets of windings, six such sets being typical - such that the magnetic fields associated with them run parallel to the axis of the machine. In each set typically are three such winds arranged along a radius, so that the outermost winding has a larger cross section than the innermost. These sets of pole pairs nest within corresponding pairs of pole pairs on the stator so that the rotor has the form of a flange rotating between the stator windings. The chassis of the stator contains yoke rings to complete the magnetic circuits. The windings have ducts for the supply of liquid helium so that the stator windings can be used as superconductors.

Title: Multiple feed rotary hearth furnace - having provision for two or more separate feed streams kept apart by baffles
Inventor: WILT JUN CHARLES R
IPC: F27B9/18
Filed: 1974-12-06
Abstract: Rotary hearth furnace for cover, side walls, ans horizontal flat rotary hearth which is mounted so that it can be rotated inside the furnace and having deflector arms mounted from the roof. It has several separate material inlets and the deflectors are so arranged that the material entering from each inlet follows a separate path round the furnace to the outlet in the centre of the furnace. The inlets are mounted round the furnace periphery and deflector rows are mounted in front of each inlet. Other deflectors can combine two streams after a certain passage through the furnace. Alternatively the inlets can be in the centre with separate outlets around the edge. Several material streams proceed simultaneously through the furnace. The deflector spacing can increase towards the centre or vice versa. The use of rotary hearth furnaces is well known but this has largely been limited the passage of a single stream through it. The furnace described allows several streams to flow through simultaneously.

Patent DE-2511470-A1 (DE)
Title: Sound quenching switch for sound-cine camera - has ganged switch to cut off oscillator when film drive switched off
Inventor: SCHMIDT-RADEFELDT ULRICH ING G
IPC: G03B31/02
Filed: 1975-03-15
Abstract: The sound cine camera is fitted with a ganged switch (9, 10, 4) with one set of contacts operating on the cine drive and the sound recording circuits (7, 13) of the camera, while the second set of contacts disconnects the oscillator (8) from the power supply (5). The oscillator (8) pre-magnetises the tape track prior to recording and when it is switched off then the sound recording stops immediately. This eliminates spurious recordings on the sound track due to the inertia in switching off the amplifier, from capacitor discharge, and the inertia in the film drive. Although the drive motor (2) continues to run for a little while the sound is immediately switched out.

Title: Aerial lightning protection circuit - comprises spark gap, fast fuse and surge diverter
Inventor: BODEMANN GERHARD DIPL ING
IPC: H01Q1/50
Filed: 1975-11-13
Abstract: To protect the equipment connected to the aerial (1), and anyone working thereon at the time, from the consequences of a lighting strike diverter elements and a fuse are connected to the aerial lead. Directly coupled to the antenna is a spark gap (2) one side of which is at earth potential. A fast acting fuse (3) is in series with the aerial lead, and on the side of the output terminal (5) a surge diverter (4) is provided, also connected to earth. Acting in combination, these elements serve to limit the currents and voltages resulting from a lighting strike to acceptable values, and to disconnect the aerial. A current of 100kA can be interrupted in 10 microseconds. The remaining voltage surge is of low energy content and can be suppressed by conventional diode circuits in the equipment input stage.

Title: DC current measurement without conducting connection - has current flowing through winding on ferromagnetic core with second winding
Inventor: PUSKAS DJORDJE DIPL ING
IPC: G01R15/20
Filed: 1976-01-15
Abstract: The second winding (W2) on the core (K) carries an adjustable compensation current (IK). Its direction is such that magnetic fluxes generated by the two d.c. currents (IM,IK), and determined by the number of amperturns in windings (W1,W2) are of opposite senses. The core (K) has an air-gap (L) in which a Hall generator (H) is placed. When the two magnetic fluxes cancel each other out, the Hall generator voltage is zero, and this is detected. A control unit (ST) continuously measures the compensation current and thus, taking into account numbers of turns in windings (W1,W2) also the measured current.

Title: Propulsion for medical probes or endoscopes - uses inflatable chambers to imitate amoebal propulsion principle
Inventor: WALTERSPIEL JUAN N
IPC: A61F2/958
Filed: 1976-01-31
Abstract: The propulsion device for probes or endoscopes in medical use artificially imitates the pseudopodia produced by a amoeba to propel themselves, in the form of a wrapper for the probe. T his wrapper forms the base for a wrapper for the of elastic material, constructed with internal ribs, or varying wall thickness so that on inflation they deform unevenly. If they are then in contact with another surface press. is exerted on the wrapper to move in its own plane. The effect can also be obtained by having subdivisions in the chambers with air flow through them unrestrained in one direction and through a spring-loaded valve in the other. orderly movement in the desired direction is obtained by the co-ordinated inflation and deflation of a number of suitably arranged chambers.
